MITRE ATT&CK

T1059.001 JavaScript/JScript T1204.002 Malicious File

The PDF file was flagged as malicious by an ML classifier with high confidence. It contains embedded JavaScript streams that exhibit obfuscation techniques, including hex escape sequences and long encoded blobs. The primary purpose of the script appears to be downloading and executing a second-stage payload from the embedded URL: http://www2.simplescaners.it.cx/?ele7r=ic%2FSm6%2FY4dKW4c7XoJaklquZ2eDRdKSkmaKmoMisl5Ggi%2Bbmop2YaqqmoaapnpWZz9Srl6aki83HmeSwu8G7ktXcx56hi%2BWX.

Heuristics 4

Suspicious extracted artifact medium EXTRACTED_FILE_STATIC_TRIAGE

One or more files extracted from inside this sample matched static suspicious-content checks such as script obfuscation, encoded payload blobs, packed data, or execution/download terms.
JavaScript action low PDF_JAVASCRIPT

PDF contains a /JavaScript action. Generic JavaScript is common in benign forms; specific dangerous APIs are scored by separate rules.
Embedded JS stream low PDF_JS

PDF references a /JS stream. Generic JavaScript is common in benign forms; specific dangerous APIs are scored by separate rules.
Embedded URL info EMBEDDED_URL

One or more URLs were extracted from the document. The URL itself is not a detection — see the per-URL labels for which channel (macro, JS, link annotation, document body, ...) reached each URL.
